You're gonna need a decoupler between your CLD titles and your MLV....Closed cell foam works great. The MLV needs to be decoupled in order to "block sound"
Also, if there are any resonances left over, IF the MLV is in direct contact with the resonances, the resonances will pass through the MLV if there is not a decoupler in place..
Sheets of CCF are cheap
I agree. That’s why I buy my MLV with closed cell foam attacked already. That way you do it once. With CLD your wasting your time and $$$ doing more than 25% of the sheet metal.
